At the centre of every large galaxy lives a giant black hole that swallows gas or dust clouds that stray too close. As matter spirals inwards, it is compressed into an accretion disk. By the time it falls into the black hole, the matter is so hot that muc

Researchers are attempting to create an Earth-size virtual instrument called the Event Horizon Telescope; a worldwide network of radio telescopes powerful enough to snap a picture of the supermassive black hole at the heart of our Milky Way galaxy.

The Einstein Rings. The Hubble Space Telescope revealed a never-before-seen optical alignment in space. The pattern caused by the bending of light from 2 distant galaxies strung directly behind a forground massive galaxy, like 3 beads on a string.

Looking through the physics book I came across the black hole. If you went through a black hole your body would be stretched, flattened, and eventually pulled apart. This is on page This has to deal with Chapter 7 Gravitation.
